Well in a binomial expansion we need to remember the formula (1+x)^n = 1 + nx + (n(n-1)(x^2))/2! + (n(n-1)(n-2)x^3)/3! + ... (I can draw this out properly on the whiteboard app)There is another formula bu...

√(4x⁸) = √4 x √(x⁸) = 2 x (x⁸)^1/2 = 2x⁴
Remember that (xⁿ)^p= x^np.

In animal cells there will be centriolesIn animal cell there will be no cell plate formation/ there will be constriction of the cytoplasm

A good way to approach this question is to first expand the brackets . This gives 12x² - 21x + 20x - 35 (remember to take the negative seven into account). We can then simplify this to give 12x...

5x2 – 2x – 3x2 + 6x – 21= 2x2 + 4x − 21
